emerge --info app-arch/snappy

I recently started getting this message after emerge:

!!! existing preserved libs:
>>> package: app-arch/snappy-1.1.7
 *  - /usr/lib64/libsnappy.so.1
 *  - /usr/lib64/libsnappy.so.1.1.7
 *      used by /usr/lib64/libQt5WebEngineCore.so.5 (preserved)
 *      used by /usr/lib64/libQt5WebEngineCore.so.5.11.3 (preserved)

I don't recall ever installing snappy, so I'm not sure why this is a thing, but sure enough, /usr/lib64/libsnappy.so.1 and /usr/lib64/libsnappy.so.1.1.7 both exist.

Furthermore, 'equery belongs /usr/lib64/libsnappy.so.1' and 'equery belongs /usr/lib64/libsnappy.so.1.1.7' both don't find any packages.

So, I emerged app-arch/snappy, then removed it. Both processes looked fine, but those two files remain. No package collisions were reported on merge, and portage reports those two files, in addition to libsnappy.so, which DOES seem to be properly removed.

dev-qt/qtwebengine properly depends on app-arch/snappy, so perhaps the problem will go away when you uninstall dev-qt/qtwebengine. In any case, there is no bug here. Please use our forums, mailing lists and IRC channels for support next time.
